Calling the Guile compiler often causes this BDWGC error: “Too
many root sets”.
scheme@(guile-user)> (define-syntax-rule (repeat n expr expr* ...) (do
((i 0 (1+ i))) ((eqv? i n)) expr expr* ...))
scheme@(guile-user)> (use-modules (system base compile))
scheme@(guile-user)> (repeat 10000 (compile 5))
Too many root sets
Abandon (core dumped)
Any idea what is going on here? Should I report it as a bug?
Is there a workaround?
Interestingly:
scheme@(guile-user)> (define-syntax-rule (repeat n expr expr* ...) (do
((i 0 (1+ i))) ((eqv? i n)) expr expr* ...))
scheme@(guile-user)> (use-modules (system base compile))
scheme@(guile-user)> (repeat 10000 (compile 5 #:to 'bytecode))
scheme@(guile-user)> (use-modules (system vm loader))
scheme@(guile-user)> (repeat 10000 (load-thunk-from-memory (compile 5
#:to 'bytecode)))
Too many root sets
Abandon (core dumped)
So the problem lies in the VM loading infrastructure. (This is
as far as I can investigate for now.)
